Hall made a limited range of figures, but he had an affinity for lions. I have recorded small lions that I attribute to Hall, as well as large ones. The lion below titled WALLACE has bocage flowers that confirm a Hall attribution. I believe this lion would have been made around 1828, when the lions Wallace and Nero were baited.
Hall is thought to have been potting from 1818 until the 1850s. He made early Staffordshire figures, but he also made figures into the Victorian period. Change in any industry is evolutionary rather than revolutionary, and so clay bodies whitened slowly over the nineteenth century. To top it, our assessment of whiteness is a subjective judgement. John Howard noted that the deer figures he sold had quite white bodies, and, for that reason, he dates them at around 1840.
